Yeah, it looks like the server is down.
1. is there a way to use maps that i parse directly from the osm site? it doesn't seem to pull up the bin files that i place in the roadmaps directory.
Roadmap takes the binary files from the proxy and compiles maps from them. There may be a way to take the manually downloaded bin's and compile then with the (command line) buildmaps_osm binary. But I haven't tried it yet.
2. are the precompiled maps from the roadmap site not vector or osm maps? what's the advantage of getting osm maps?
The precompiled maps on the Roadmap site are based on U.S. Census Bureau Tiger Data. They are vector maps. Roadmap was designed to use these maps. (Some features like address lookup only work with Tiger maps.) OSM support is new and in Beta... The primary reason for OSM is to make RoadMap useful to people outside of the U.S.
Ok, it looks like the POI engine uses google data, which i always have a couple of issues with.
1. google doesn't always give you the nearest POIs for whatever reason.
2. i can only get 10 POIs at a time. any way to get all returned results?

lastly, i can't for the life of me figure out how to map a simple route--i see an array of options for trips, places, routes, tracks, etc. how can i enter an address/poi and get directions to that point? can it be done onboard yet, or does it need to go through google?
You've got a couple of options-
1. Route by address- go to 'file->get google route by address', enter your start and destination address and go.
2. Route on the map- Click your destination, then long-click it and select 'New Route to Selection'. Then go back to your location (press 'g'), click on it then long-click and select 'Set/Prepend route start'. Then goto 'file->fetch google route', done.

Both of these options use google to route. Onboard routing is not implemented yet. (There's a branch of Roadmap called Roadmap-Editor which has routing and a small group of coders including myself trying to port the functionality over to RoadMap. But it's a lot of work... Basically, It's coming, but don't hold your breath and wait for it.

hope this helps,
